The headset blends both virtual reality and augmented reality, a technology that overlays virtual images on live video of the real world.

这款耳机融合了虚拟现实和增强现实技术，后者是一种将虚拟图像叠加在现实世界的实时视频上的技术。

Any simple magnifier consists of a single converging lens, which produces a virtual image that enlarges an object.

任何简单的放大镜都由一个 会聚透镜组成，它会 产生放大物体的虚像。

We also studied simple magnifiers and how to generate an enlarged virtual image.

我们还研究了简单的放大镜以及 如何生成放大的虚拟图像。

The new Apple Vision Pro looks like a pair of ski goggles and lets people overlay virtual images on live videos of the real world.

新款Apple Vision Pro看起来像一副滑雪护目镜，可以让人们将虚拟图像实时叠加在现实世界里。

This image is very small, but the eyepiece acts as a magnifier, forming a large, virtual image for the observer to view.

这个图像非常小，但目镜 起到放大镜的作用，形成一个大的虚拟 图像，供观察者观看。

And ideally, this virtual image forms just past your near point, because if it were closer, you wouldn’t be able to focus on it.

理想情况下，这个虚像刚好在你的近点之后形成，因为如果它更近，你就无法专注于它。

You’re seeing a virtual image, because the light rays that make up your reflection aren’t actually converging to form an image of you.

您看到的是虚像，因为构成您反射的光线实际上并未汇聚成您的图像。

And ideally, this virtual image forms just past your near point, because if it were closer, you wouldn't be able to focus on it.

理想情况下，这个虚拟图像会在 您的近点附近形成，因为如果它更近， 您将无法专注于它。

Since the leaf is inside the focal point, the rays diverge, and the lens forms a virtual image that’s much larger than the original object.

由于叶子在焦点内，光线发散，镜头形成比原始物体大得多的虚像。

Since the leaf is inside the focal point, the rays diverge, and the lens forms a virtual image that's much larger than the original object.

由于叶子在焦点内，光线 发散，镜头形成 比原始物体大得多的虚像。

You're seeing a virtual image, because the light rays that make up your reflection aren't actually converging to form an image of you.

你看到的是一个虚像，因为构成你反射的光线实际上并没有会聚形成你的图像。

But when you look at the leaf through the lens, the virtual image is larger than the actual object, so it subtends six degrees of your vision.

但是当你通过镜头看树叶时 ，虚像比实际物体大， 所以它对着你的视线六度。

And just like with telescopes, the real image is just inside the focal point of the eyepiece, generating a large virtual image for the observer to view.

就像望远镜一样，真实图像 就在目镜的焦点内，生成 一个大的虚拟图像供观察者观看。

In order to find the magnifying power of the lens, you just divide the angle subtended by the virtual image by the angle subtended by your unaided eye.

为了求出镜片的放大倍率 ，只需用虚 像对角除以肉眼对角。

But the alternative is a virtual image – an image where the light rays don’t actually converge, so your eyes construct an image as if the diverging rays originated from a single point.

但另一种方法是虚像——光线实际上并不会聚的图像，因此您的眼睛会构建一个图像，就好像发散的光线源自一个点。

But the alternative is a virtual image – an image where the light rays don't actually converge, so your eyes construct an image as if the diverging rays originated from a single point.

而另一种选择是虚拟图像 - 光线实际上不会会聚的图像，但是您的眼睛会构建一个图像，就好像不同的光线来自一个点一样。

When we’re looking at an object through a diverging lens, our eyes imagine that the diverging rays originate from a location where the rays don’t actually begin, so the lens generates a virtual image.

当我们通过发散透镜看物体时，我们的眼睛会想象发散光线来自光线实际上并未开始的位置，因此透镜会产生虚像。

When we're looking at an object through a diverging lens, our eyes imagine that the diverging rays originate from a location where the rays don't actually begin, so the lens generates a virtual image.

当我们通过间隔透镜看到一个物体时，我们的眼睛会想象发散的光线来自光线实际上没有开始的位置，因此透镜会产生一个虚像。

While a single ray of light still goes through the very center of the lens, the other two rays take slightly different paths, resulting in a virtual image forming on the same side as the object itself.

当光线从中心通过时，剩余的光线会发生略微不同的衍射，从而在身体的同一侧产生一个假想的图像。
